I've watched tons of plaster-use instructional videos and this is my favorite so far. Comprehensive and still to the point.

A bit confused at the end usage - I thought this would be a slip-cast mold but you ended up press-casting? Wouldn't this mold work just fine for a liquid slip cast?

Now I am going to try making a mold that I have been thinking about for years. One question: do you have a video on making those 4 adjustable pieces that you used for the sides of the square mold?

To determine the volume of a object fill a container with water then submerge the object in it and see how much the water rises. You have two way to figure out how much volume that is: 1) If the walls of the container are vertical than you can measure the how much the height of the water changed and multiply that times the area of the opening (like you showed for figuring the mold container volume. 2) You can draw a line for where to water rose to and remove the object then add water until it reaches the line. The volume of water you added is the volume of the object.

Hello, I have benefited a lot from your mold making video, thank you so much. I have a problem. All the people who teach mold making are always teaching how to make molds for clay materials. No one shows how to make molds to make hollow concrete materials. For example, one centimeter wall thickness, hollow inside, open mouth and closed bottom. Can you make a video showing how to make a concrete vase, pot or any container mold?

@dinaatanassova6310 2 жыл бұрын

I am interested in making cement molds. I saw that they are made out silicon material, you know the one they use for baking silicon molds. They can be purchased as ready molds or you can mix silicone mixture to make your own molds. I tried to use gypsum mold for cement, but it was a disaster because cement (liquid) acts differently than clay (liquid). Clay can get off the plaster easy but cement will get glued to plaster mold.

Hi, Halil, the mould your are talking about would have to be rotated while curing to achieve that. Very advanced way of casting. And you need a silicon skin mould with hard case.

@halilbalaban1056 2 жыл бұрын

Hi @@Cuckoo23, thank you very much for your courtesy to reply. I know how to make a standard silicone mold. I don't know how to apply two-piece stays to hollow objects as clay artists do. And no one makes silicone molds for hollow objects. Thank you again. I send greetings from Turkey, love, respect, big hugs, good night.

@kaglaw 2 жыл бұрын

@@halilbalaban1056 i think you just fill the inside of the container. I have seen the inside stuffed with paper or rocks and then topped off with clay or silicon. That prevents the slip from filling the inside. Once finished making the mold, you can remove the filler material. I am planning on making a set of coffee mugs. Thanks

Foam sticks to plaster, so do not try to cast a foam object in a plaster mold directly. Paint layers of latex into the mold first. Also, use something like Ultracal 30 or Hydrocal plaster for non-clay casting.

You can even pour the slip into the mold, waiting a few minutes then pouring it out. That’s called slip casting.

Yea, I don't know why you'd push the clay in there rather than just slip casting it. Slip casting way simpler, so I'm confused.

Why use clay that dry? It seems easier to mix clay with water until it's a thick slurry and pour it and let it dry a bit then pour the excess out.

Slip casting

@Heartwing37 5 күн бұрын

He’s not slip casting, which is what you’re describing. I’m not sure if this technique is called the same thing as in glass working but we would call using this process slumping…because the media “slumps” into the mold. I’ve not seen pottery done like this but I’m a novice. I think most people slip-cast, which is what you describe. Interesting! Ah, he just called it “press molding”.

At 9:04 the ratio of H20 : plaster, is the a volume or mass ratio? At 9:09 the screen shows 1ml H2O = 1g H2O but the voice says 1ml water = 1g PLASTER. Were do mls come into play? You appeared to use only a scale so I am definitely confused, did you go 1:1 by mass OR 1 H2O : 1.3 Plaster by mass?
